Solution

1. Preparation

Gather tools: Socket set, multimeter, screwdriver set, and a trim removal tool.
Ensure vehicle is parked on a level surface and ignition is off.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the power window fuse and check for continuity using a multimeter.
- Tools Required: Multimeter
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check Window Switch

Use a trim removal tool to carefully detach the window switch panel from the door.
Disconnect the switch connector and test for voltage using a multimeter while pressing the switch.
- If no voltage is detected, the switch may need to be replaced.
- Tools Required: Trim removal tool, multimeter

4. Inspect Window Motor

Remove the door panel using a socket set and screwdriver to access the window motor.
Inspect the window motor for any signs of damage or excessive wear.
If the motor is faulty, replace it by disconnecting the wiring harness and unbolting it from the door.

5. Examine Wiring and Relay

Visually inspect the wiring harness for any signs of fraying, corrosion, or disconnection.
If the wiring appears intact, check the relay by swapping it with another similar relay in the fuse box to test functionality.
- Tools Required: Socket set
